Adds 5 emerald tools and 4 emerald armor pieces. Also adds 1 new challenge.
Emerald tools and armor follow vanilla Minecraft crafting recipes. Emerald tools ignore the hit penalty from villagers (Villagers, Iron Golems, and Wandering Traders). For example, attacking a villager with an emerald sword will not increase trade prices or make Iron Golems target you.
Emerald tools and armor have performance that sits between iron and diamond.
